Why aluminium

Aluminium is among the most widespread elements in nature and among the greenest in terms of energy cost of production. It is a light and sustainable metal, practically eternal and completely recyclable for an infinite number of times. It is resistant to corrosion and is easy to work at both high and low temperatures. It is also characterized by high electrical, thermal and sound conductivity and a reflective capacity that favours energy saving.

For 60 years aluminium has been METRA Building’s ally: a deep bond that is determined by knowledge that concerns both the raw material and the entire production chain. Decades of updating, investments in technology and know-how make METRA Building products recognized worldwide as real excellence.
